Different result clearblue fertility monitor and advanced digital ovulation tests

[Mos9]

I wonder if anyone could shed some light? First cycle using the clearblue fertility monitor. Now on CD10 ( or cd11 according to ovia) just got my first high result using fmu. Also bought the clearblue advanced digital ovulation tests to use in the evening in case the morning urine misses my surge . However after just testing now this has come up with a low result ? Which do I trust, the fertility monitor or opk?

The sticks are probably reading low because you have started using them later in your cycle. They should still pick up your surge (solid smiley) but I would use the monitor readings to work out your ‘high’ days.

Okay that makes sense! I only started using the sticks yesterday. Maybe I should've started earlier on. Thank you :)

Still low on the digital opk and high on the fertility monitor. Used the same urine sample today too. Starting to worry that maybe there's something wrong with me not the opks. Especially as it's my first cycle using the fertility monitor

I’ve got the monitor. First cycle I got 4 high days before peak. That’s not unusual. Second cycle I got 3 highs before peak. It’s my understanding the the monitor is more sensitive x
